To all 1072 0722 it may coaccmt."

Be it known that I, Emit Ersnnnnrsaa citizen. of the Sw1ss Republic, anda resi- -dent of Perlen, near Luzern, Switzerland,

have invented a new and useful Improved Method of Burning AqueousLiquids Containing Sulphite Waste Lye. of which the Following is aspecification.

With sulphite waste lye it is necessary to expel its contents ofwaterbefore the combustible substances it contains can be burned vention hasnothing to do with the combustion of liquid fuels, such as oil and thelike,

which 'burn like gases; the invention relates solely to thecombustionoct sulphite waste lye which contains much water which is tobe removed before the combustible components are burned.

In order to render this procedure as economical as possible, thesulphite waste lye is preferably strongly concentrated before it isburned. As, however, such a strongly concentrated lye is pretty thick orviscid. it is not atomized, but a continuous jet of it is conducted inregulated amounts to the several portions ofvthe grate, or a certaindistinct portion of it, in such a manner that the grate is uniformly fedwith it, or uni formly covered with the combustible componentsrespectively. If this manner of operation is employed the jet of theconcentrated lye may be supplied also from another point than the rearof the grate or furnace. Supplying the concentrated lye in the form 0f acontinuous jet is advantageous in so far as the correspondingly largenozzle is not clogged up so easily as is the case when a plurality ofsmaller nozzles is made use of.

The mechanical means for carrying my invention into practice areillustrated, by way of example, in the accompanying draw- .in Fig. 3.

Figure 3 is an axialsection through some parts of a lye supplying device which is tobesubstituted for that shown. in the lefthand upper portion of Fig. 2and'is drawn on a greatlyenlarged scalein comparison to :Fig. 2.,.Figure 4 is a transverse sectlon through the parts shown Referring to F'igu'rell, his the firejspace of a furnace having a'tra-velling grate(Z, c

the right in the figure. The liquid or lye to be burned is introducedintothe space I) from a point located upon the fire-bridge where thereis provided 'a supply tube er encompassed by a cooling tube 6 and havingone or. several .atomizlng nozzles ,The

tubQS d jand .6 extend into the fire space through thes'ide-walls ofthe-furnace. The 'lyeis introduced under pressure into the tube wandthen projected and sprayed into the fire space towards the gratewherethe combustible comppnents of the liquid are burned. Theftubesla;and a with the nozzle 01'' nozzle'sare preferably rotatable at least insuch a degree that the lye can be proj ected and sprayed over the entirelength of the grate.

The configuration of the nozzle or nozzles f may be such that the-liquidescapes in the Whilst the supplying or distributing device illustratedin Figure l is intended for unconcentrated or but little concentratedlye, Figure 2 shows, as another example, means to be employed if the lyeis pretty strongly concentrated. 1 is a delivery aperture provided in astationary wall or the like extending upwards from the fire-bridge.Behind said apertureis a guide tube or nozzle 2 which is supported by aball-shaped meme her 3 that may be turned in any direction so as tothrow the jet of the concentrated liquid to any desired part of thegrate. The means for thus actuating said member 3 may be of anyappropriate design, and the tube or nozzle may be connected with aflexible tube V and the aperture is a substitute for the aperturef ofFlig. 1 or for the aperture 1 of Fig. 2. lVithin-the tube 6 is astationary wall or disk forminga bearing for 'a shaft 9 havinga rotarydisk 7 secured to it. The rim of this disk is provided with obliquerecesses 8,-the angularityof'which is'diiferent in the direction tothe-shaft 9 (Fig. '3), as well as in the plane of the disk 7 (Fig. 4E),and such recesses are provided on both-sides of the disk: The lyeprojected and sprayed by the disk, or from anyone of these recessesrespectively, is obviously correspondingly distributed over, the grate,and the number and shape of the recesses maybe such that every portionof the "grate is 'fedwith lye, or with the combustible componentsof thesame respectively.

I claim: y

1. The method of utilizin'g sulphite waste lye in furnaces, eonsistingfin introducing the lye in counter-current onto a'fire'-burning ona grate'at the end counter to the charging end for the fuel proper to'beburned onsaid grate. ,p y

2. The method of'utili'zingsulphite Waste lye in furnaces, consistinginintroducinglthe lye in counter-current onto a fire burning onatravelling grate at the end counter to the charging end for the fuelpro-per to be burned on said grate.

3. The method of utilizing sulphite waste lye in furnaces, consisting inintroducing the lye in concentrated state and in countercurrent onto afire burning on a grate at the end'counter to the charging end for thefuel proper to be burned on said grate.

A. The method of utilizing sulphite waste lye in furnaces, consisting inintroducing thelye in finelyv distributed state and in counter-currentonto a fire burning on a grate at the end counter to the charging endfor thefuel proper to be burned on said grate. Y

The method ofutilizing sulphite waste lye infurnaces, consisting inintroducing the lye in a continuous jet and in countercurrent onto afire burning on a grate at the end counter to the charging end for thefuel proper-to be burned on said grate.

, 6. The method of utilizing sulphite waste lye 'in' furnaces,consisting in introducing,"

the lye "in a continuous jet and in countercurrent onto a fire burningon a grate at the 'end' counte'r'to the charging end for the fuel properto be burnedon said grate, and directing ,sai'd jet by and by onto everypart ofthe grate area.

In testimony whereof I'affixmy signature in presence of two witnesses.
